Trial summary

Awake fibreoptic intubation (AFOI) is a classic and standard method for some special patients which is also difficult for anesthesiologists to learn and master. The procedure is sometimes hard and often takes about 20-30 min. Most of patients have a strong sense of discomfort. Read more about this study

About this study

Awake fibreoptic intubation (AFOI) is a classic and standard method for some special patients which is also difficult for anesthesiologists to learn and master. The procedure is sometimes hard and often takes about 20-30 min. Most of patients have a strong sense of discomfort. Investigators conducted the research to study the simplification and feasibility of AFOI.

Read the detailed description

Many studies have studied the sedative drugs and regional anesthesia related to awake intubation. However, several problems of AFOI are existing including long operation time, patients' strong discomfort, coughing and resistance. And, to investigators' knowledge, there was a lack of a fixed procedure for the implementation of AFOI. Investigators conducted the research and aimed to study the simplification and feasibility of a new AFOI method based on years of clinical theory, practice and experience.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Awake fiberoptic intubation (AFOI)Procedure or surgery

    With forty patients (ASA I~II, aged 18~75, simulating cervical instability injury) recruited to be operated on under general anesthesia, two experienced anesthesiologists performed the whole procedures within the study. Pre anesthetic interview was taken to illustrate the procedures of tracheal intubation to the patients. The simplified method consisted of three parts: conscious sedation, regional anesthesia and intubation. The time of AFOI, rate of one-time intubation success, hemodynamic parameters, pulse oxygen saturation (SpO2), rate of amnesia of the intubation, patients' satisfaction, and relative complications were recorded accordingly.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The average total time of Awake Fiberoptic Orotracheal Intubation (AFOI)

    The time from the midazolam injection to positive end tidal CO2 acquired (Minutes)

    Measured: End of the AFOI

  2. The rate of one-time intubation success.

    All steps are successful once (Percentage)

    Measured: End of the AFOI

Secondary outcomes (10)
  1. Systolic blood pressure, SBP (mmHg)

    SBP is used to assess hemodynamic fluctuations

    Measured: During the AFOI

  2. Diastolic blood pressure, DBP (mmHg)

    DBP is used to assess hemodynamic fluctuations

    Measured: During the AFOI

  3. Heart rate, HR (bpm)

    HR is used to assess hemodynamic fluctuations

    Measured: During the AFOI

  4. Rate of amnesia of the intubation

    It is used to assess anterograde amnesia of midazolam

    Measured: On the first postoperative day

  5. Ramsay sedation scale

    1= anxious or restless or both, 2 = cooperative, orientated and tranquil, 3 = responding to commands, 4 = brisk response to stimulus, 5 = sluggish response to stimulus, 6= No response to stimulus

    Measured: During the AFOI

  6. Patients' satisfaction

    1 = excellent, 2 = good, 3 = fair, 4 = poor

    Measured: On the first postoperative day

  7. Unexpected coughing

    Unexpected coughing was evaluated with 4 score (1=none, 2< 3 times unexpected slight coughing comparable to 'clearing ones' throat', 3≥2 times, mild unexpected coughing lasting less than a minute, 4=persistent unexpected coughing)

    Measured: During the AFOI

  8. Relative complications

    Such as arrhythmias, bleeding or sore throat

    Measured: End of the surgery and the first postoperative day

  9. Vocal cord movement

    1 = open, 2 = moving, 3 = closing, 4 = closed

    Measured: During the AFOI

  10. Hypoxic episode

    SpO2<90%

    Measured: During the AFOI

Questions about this trial

What is this clinical trial studying?

An observational study of Anesthesia and Trachea, run by Fudan University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The average total time of Awake Fiberoptic Orotracheal Intubation (AFOI) (time frame: End of the AFOI). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Jan 2019.
